Abstract: The Eastern Afromontane region of Africa is characterized by striking levels of endemism and species richness. Therefore, it was recognized as the Eastern Afromontane biodiversity hotspot (EAMBH) with numerous endemic plants and animals including mammals. Some parts of EAMBH (e.g. Ethiopian Highlands) are still under-represented in terms of biodiversity research in comparison with areas where sampling was relatively intensive in the last decades (e.g. Albertine Rift). This thesis describes genetic diversity, evolutionary history and taxonomy of several rodent species inhabiting mountain areas of Eastern Africa and Angola with a special focus on neglected areas such as Ethiopian and Angolan Highlands. Molecular-genetic analyses detected considerably higher diversity of small mammals than previously expected. Several candidates for new species were suggested and some of them also formally described based on phylogenetic and morphometric analyses. Molecular dating placed most of the diversifications into the eras of Pliocene and Pleistocene confirming the hypothesis that Plio-Pleistocene climate fluctuations together with topographically diverse landscape of Eastern Africa contributed to the high level of species diversity observed today.
